CMI at Oak Ridge National Laboratory conducted the activity for this highlight
Innovation
Energy efficient and cost-effective membrane solvent extraction (MSX) technology has been developed to recover heavy rare earth elements (HREEs) from a wide range of end-of-life (EoL) electric vehicle (EV) magnets for clean energy, vehicle technology, and defense applications.
Achievement
Successfully demonstrated the separation of dysprosium (Dy) from EV magnets (obtained from Chevy Volt transmission drive with 8.9 wt.% Dy) with >95 % recovery and >99.9 wt.% purity.
Significance and Impact
MSX Technology provides a potential pathway for industry deployment to domestically produce HREEs with high purity and recovery from complex EV magnets feedstock.
Hub Target Addressed
Win industry adoption of one technology to produce HREEs using domestically available EoL EV magnets.
